Implementation of a dual platelet inventory in a tertiary hospital during the COVID-19 pandemic enabling cold-stored apheresis platelets for treatment of actively bleeding patients.

BACKGROUND: To increase preparedness and mitigate the risk of platelet shortage without increasing the number of collections, we introduced a dual platelet inventory with cold-stored platelets (CSP) with 14-days shelf life for actively bleeding patients during the COVID-19 pandemic. STUDY DESIGN AND METHODS: We collected apheresis platelet concentrates with blood type O or A. All patients receiving CSP units were included in a quality registry. Efficacy was evaluated by total blood usage and laboratory analysis of platelet count, hemoglobin, and TEG 6s global hemostasis assay. Feasibility was evaluated by monitoring inventory and a survey among laboratory staff. RESULTS: From 17 March, 2020, to 31 December, 2021, we produced 276 CSP units and transfused 186 units to 92 patients. Main indication for transfusion was surgical bleeding (88%). No transfusion reactions were reported. 24-h post-transfusion patient survival was 96%. Total outdate in the study period was 33%. The majority (75%) of survey respondents answered that they had received sufficient information and training before CSP was implemented. Lack of information about bleeding status while issuing platelets, high workload, and separate storage location was described as main reasons for outdates. DISCUSSION: CSP with 14-days shelf life is a feasible alternative for the treatment of patients with bleeding. Implementation of a dual platelet inventory requires thorough planning, including information and training of clinical and laboratory staff, continuous follow-up of practice and patients, and an easy-to-follow algorithm for use of CSP units. A dual platelet inventory may mitigate the risk of platelet shortage during a pandemic situation.

How do I implement a whole blood-based blood preparedness program in a small rural hospital?

Civilian and military guidelines recommend balanced transfusion to patients with life-threatening bleeding. Early start of transfusion has shown improved survival. Thus, a balanced blood inventory must be available in all levels of health care to ensure early stabilization and damage control resuscitation of patients with bleeding. Whole blood has been reintroduced as a blood product for massive bleeding situations because it affords plasma, red blood cells, and platelets in a balanced ratio in a logistically advantageous way. In this article, we describe how to establish a whole blood-based blood preparedness program in a small rural hospital with limited resources. We present an implementation tool kit, which includes discussions on whole blood program strategies and the process of developing detailed procedures on donor selection, collection, storage, and transfusion management of whole blood. The importance of training and audit of the routines is highlighted, and establishment of an emergency walking blood bank is discussed. We conclude that implementation of a whole blood program is achievable in small rural hospitals and recommend that rural health care facilities at all treatment levels enable early balanced transfusion for patients with life-threatening bleeding by establishing protocols for whole blood-based preparedness.

A patient with severe COVID-19 treated with convalescent plasma. / Pasient med alvorlig covid-19 behandlet med rekonvalesensplasma.

BACKGROUND: COVID-19 can lead to life-threatening disease. While awaiting vaccines or documented specific therapeutic agents, several alternative treatment options are under investigation. This is a case report of the first COVID-19 patient treated with convalescent plasma in Norway. CASE PRESENTATION: A patient with severe COVID-19 on prolonged mechanical ventilation, who was PCR SARS-Cov-2 positive on day 22, was transfused with convalescent plasma on day 31 and tested negative for SARS-CoV-2 the following day. The patient gradually improved and was weaned from the ventilator and discharged alive from the ICU on day 63. INTERPRETATION: This case report concerns one patient with clinical improvement after convalescent plasma transfusion. A SARS-CoV-2 test was not performed immediately before transfusion and the complexity of intensive care treatment makes it difficult to draw any conclusions on the potential effectiveness of this treatment. However, this case report is encouraging with regard to planned trials with convalescent plasma.
